They don't like the FL cans because they can't dim them? Or the cost associated with dimming them?
There's other ways to solve that. Our church did a ceiling remodel and the same issue came into play: FL: cheaper on energy, but huge initial cost to dim them. As the sanctuary needed about 100 cans, I suggested to combine them on 8 different switches where in some rows (in the front) every other 3rd would be able to be controlled separately and the back rows to have every other row on different switches. Took a little work to design all these combos, but everyone's pretty happy with the outcome.
Try to find what they want to accomplish, for instance they might have a screen where they want to dim he light near the screen. Leaving only 5 lights on out of 20 will accomplish same effect. Or they want to have the sanctuary dim, while the front is bright. Having the middle row on in the seating while the rest are off, and the front fully lit will accomplish again same effect as a dimming.
Another issue to consider is, keep in mind this: is not like the lights will be on 24/7, worst case scenario they'll probably run 20 hrs a week, which will not that big of a difference comparing to other places where lights are on for 20hrs a day. So that will not a big selling point with them (saving energy). In such places the biggest selling point is the huge amount of resources it takes to replace ONE LAMP. At 30' you pretty much need a lift, so if they really want to go incandescent I'd recommend to them investing money in a lift (one of those that goes over the benches). And also mention to them that unless they gonna have a trained maintenance person to change the lamps, it'll cost them quite a bit everytime they change a lamp.
You might wanna mention they have several colors nowadays for FL, some people might be against FL because they work all day in an office with 6K lamps and they hate it.
And last: HID is OUT OF THE QUESTION. Remember that HID don't come fully back on for about 15min after been turned off. At best they'll come back on after 2-3 minutes after being turned off.
We have a increasing amount of church clients that are wanting dimmable can lights in these ultra high ceiling sanctuary's. People do not like flourescents. With all of the shift away from incandescents with the Patriot Act, is there other cost effective ways to accomplish what the customer wants? Currently I have a customer that has a 3000 sqft sactuary with a 30ft ceiling and 20ft side walls and they want can lights
We did another one recently with 250w halogens but we had alot of lamp failures due to the extreem heat. Any suggestions?
